s Claims. (01512-401) My invention relates to concrete building constructions, and more particularly to a channel insert to be initially positioned within a concrete form for embedment in the concrete structure to form an anchor slot therein, and tie members engageable therewith foranchoring to the struc-' ture. a masonry veneer or facing of brick, stone or terra cotta and the like. I

The present invention includes a channel shaped form member of comparatively thin material having a contracted or restricted slot like orifice with which are associated means for securing the channel form to the interior of a concrete form structure and spreader means for reinforcing the channel insert to enable it to withstand the pressure of the deposited concrete together with coupling means for interconnecting succeeding sections or lengths of insert channels in longitudinal alinement with each other and for closing the terminal ends of such insert to prevent the entrance of plastic concrete. There are also associated with such channel inserts, an-

chor ties which are reversible, either end thereof 1 ,unlikelyto get out of repair.

A further object of the invention is to provide economical means for attaching the insert channels to the interior of a concrete form structure,v

and for bracing the side walls of the channel inserts to enable them to resist the pressure of surrounding concrete deposits.

A further object of the invention is the duofunctional use of a commercial staple as an attachment and spreader means for the channel inserts.

A further object of the inventionis to provide improved coupling means for aligning succeeding sections of the insert channel with each other, and for engaging such coupling means therewith.

A further object of the invention is to provide improved closure means for the terminal ends of the channel inserts to prevent the entrance of plastic concrete thereinto.

A further object of the inventionis to provide a duo-functional closure and coupling member for the concrete. sections and to -provide simple and;

economical, means for detachably, connecting such meinbertherewith.

A further object of the inyention is to providean improved form of reversible anchor tie engageable within the embedded channel inserts, the

opposite ends of which are adapted for engagement therewith, whereby in whichever position the workmen may pick up i the anchor tie, it will beproperly positionedfor easy engagement with-theinserta H A further object of the invention is to facilitate; the manufacture and mode of assembly of such construction. Y

With theabove primary and other incidental objects in view, as will more fully appear in the specification, .the invention consists of the features of construction, the parts and combinations thereof, and the. mode of operation, or their equiva1ents, as hereinafter described and set forth in the claims. 1 r

Referring to the accompanying drawing, wherein is shown the preferred, but-obviously not necessarily the only form of the embodiment of the invention, Fig. 1 is a perspective view of a portion of .a concrete body, and the form therefor-partially stripped away from the concrete body to disclose a channel insert, forming an assembled aligned anchor slot insert showing a duo-functional closure and coupling'member engaged with one end portion, andillustrating the relation of the duo-functional spreader and attachmentqstaples. Fig. 4 is a detail perspective view of the closure and coupling member de-' tached from the anchor-slot insert, and the 'end of the insert adapted to receive the closure and coupling member. Fig. 5 illustrates several forms of anchor ties interchangeably engageable with the anchor slot inserts all ofwhich may be employed in the same building structure. Fig. 6,is a detail View of a modification of the spreader and attachment means. Fig. '7 is a modification wherein the legs of the attachment extend exteriorly of the channel side walls. Fig. 8 is a transverse section viewed from the bottom of Fig. 6;

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawing, I indicates a portion of a. concrete structure, and 2 the wooden present instance the side walls of-the. channel are shown convergent or oppositely flaring throughout a portion of theirextent as at 5 and substantially parallel throughout the remainder of their extent as at 6, the flaring: and parallel portions being joined by a lateral offsetor shoulder 1. While this construction is preferable anddesirable, it is not essential and the shape of the channel may be variedto meet different condi-* tions of use and in accordance withthe desiresa and preference of difierent building constructors. However the form. illustrated in the drawing has been found to be quite efficientanddesirable as well as economicalin manufacture. The channel insert is preferably, thoughnot necessarily,

provided with, outwardly extending *marginalflanges 8 to afford a contact bearing withthe' interior base of the form-wall to which the insert sition the spacer plates therewithin. 1 If so-de sired the walls of the channel inserts may be isinitially attached.

;By providing spacers orreinforcing ,members at'intervals throughout the lengthpf the anchor slot insert, such as wooden blocks or diaphragm plates 9 which conform to the shape of the'channel, relatively light material may be: employed.

The spacer plates 9 may be madefromsheet 7 metaland be provided with marginal ears or tongues Ill projecting perpendicularto the plane of the spacer plates 9 and having bearing upon the interior-walls of the channel to properly poembossed to provide projections orf bosses I'I within which are seated corresponding bosses I2 upon the tongues of the spacer plates 9. If the bosses or projections H are inwardly directed, the tongues I0, of the spacer. plates, may be perforated to engage therewith to thereby hold the spacers in properly spaced relation with each other. ;In the event that wood blocks or the spacer plates!) are employed,'ordinarynails may be driven through perforations in the channel into the concrete form 2 for temporarilysupporting the channel inserts in position to be embedded in the concrete-mounting.

However, the preferable methodof temporarily 1 attaching the insert channels to the interior base of a concrete form, is by use of ordinary com-' niercial staples l4 of a size corresponding substantially' to the width of the'slot likeoriflce 4 r of the channels. such staples I4 duo functionally serve to secure the channels to the-"concrete forms and also act as spacers .to hold the side wall above the channels in properly spaced rela- 'tion and reinforce the channel walls to resist the pressure of the concrete deposited" thereabout. Such staples l4 are driven through spaced perforations in the-wall of the channel and extend" thence through the channel insert with their points projecting through the orifice-slot 4 in 1 position to be driven into the wall of the concrete form 2 asillustrated in Fig; 1. When so driven I into the form the legs of the staple l4 rigidly resist any contractive movement of the insert channel. venient and economical, but it affords-an extremely rigid reinforcement forthe insert ohari' 7 stone.

Such construction is not only connel enabling the use of comparatively light weight and hence inexpensive material. 7

To prevent the inflow of the plastic concrete to the interior of the insert channels and also to insure proper longitudinal alignment of succeeding sections of such channel inserts, terminal 010- sures l5 are provided. These closures I5 are shaped to substantially agree with the cross sectional contour of the insert channel and are provided with marginal ears or tongues lliand I! turned in opposite directions into substantially perpendicular relation with the closures I5. The ,ears or tongues l6 extend exteriorly of the parallel portion 6 of the channel walls and are perforated for engagement over bosses or projections l8 formed in such wall portions. ,By

" squeezing or flexing the channel walls, the clo- I'I, carried by the closure member l5, form a receiving socket for locating the terminal endfof the next succeeding section of insert channel in accurate alignmentwith the preceding section.

The ears or tongues l1 extend exteriorly of the end of "the adjacent insertchannel portion.

Thus the members I5 duo-functionally serve to couple and align the succeeding sections of the anchor slot channel, and at the extremities of such inserts may serve to close the channel to exclude plastic concrete, dirt or other material.

[The anchor ties for'use with the insert chan- V nels, may be. of various forms, severaliof which areillustrated in Fig. 5. Such anchor ties are preferably, though not necessarily, stamped from sheet metal of somewhat heavier gage than that from which the insert'channels are formed. The anchor ties I9 are formed with terminal heads 20 agreeing with the interior contour of the insert channels with which the ties are engaged by inserting the heads 20 into the channel through the slotted orificed, and giving'to the tie a partial rotation into a transverseplane wherein'the enlarged head 20 will have interlocking engagement within the channeL, The head 20 of the anchor tie is shown provided with right angle shoulders or offsetsZl which seat upon the shoulders or oifsets, 1, of the channehwhile the divergent or beveled margins of the head 20 have seating engagement upon the flaring. portion 5 of the channel. When employed for attaching.

stone masonry to the face ofa concrete. structure, the anchor'ties are bent at right angles, at their outer extremities asat 22, for engagement in-a suitably positioned'hole in the facing are embedded in the mortar joints between succeeding bricks, stones'or blocks or terra cotta. To afford the necessary anchorage, the tie is perto securely anchor the masonry to the concrete structure within which the insert channel isembedded, The preferred form of anchor tie for ordinary use is that shown at 25 upon which Ordinarily, however, these anchor ties identical heads 20 are formedat the opposite terminals of the anchor tie whereby the tie is either side uppermost and either .end foremost it is ready to be quickly and easily interlockedwithin the embedded insert channel. In such case one end of the itiehas the interlocking en gagementwith the interior of the channel walls by being partially rotated into a transverse plane after insertion through the orifice slot 4, while the oppositehead 20 affords furtherand addi-" tional interlocking engagement with the mortar joints in which it is embedded. 1

While the insert channels may be manufactured in any suitable length for'ordinary com-. mercial' production, they. are manufactured in lengths of four feet each, each such section be-' ing perforated at three spaced intervals to rea ceive the attaching and reinforcing staples l4. In assembling the channel forms upon theinte-Tv rior of the concrete form structure they are sethe interior of the concrete form, spacer heads or diaphragms 9 distributed throughout the length of the liner channel at spaced intervals may be substantially identical with the terminal heads 'or closures 15, but of slightly smaller size whereby such spacer heads may be inserted within thechannel as shown in Fig. 6 wherein the oppositely extending'tongues or ears I0 will prevent the reinforcement heads a'ssumingan inclined or askew position.- Such reinforcement heads may be detachably engaged with the slot liner or channel in a manner quite similarto the interengagenient ofthe terminal heads therewith, that is by'means of theperforations H engaging over bosses or projections 12 in' the side walls of-tne liner channel.-

The terminal heads 20 of the anchor. ties substantially conform to the flaring or convergent portions of the side walls of the channel or liner, and such-anchor ties have neck'portions adja cent to the flaring heads 20 which agree in width with the space between the parallel portion 6 of the slot liner or channel. Such neck portion of the tie, by its engagement with the interior substantially parallel surfaces of the portions 66 of thechannel, hold the anchor tie against wabble movement and maintain succeeding anchor ties engaged'with the slot liner channel in parallel alignment with each other. A slight right angle shoulder oroffset 2|, adjacent to the flaring head 20, is preferably, though not necessarily, provided upon the anchor tie members for seating engagement with the shoulder or oifset I of the channel member.

In Fig. '7 there is shown a modification wherein a short spacer 22 which may be a short wire or rod, but which for economy is preferably a small nail or wood block is interposed between the portions 5 of the side walls where its ends seat within the sockets formed by outwardly extending bosses or projections [8 formed in the wall portions 5 at spaced intervals throughout the length of the insert. Such spacer resists contraction of the insert channel under pressure of the deposited concrete and maintains the slot 4 of proper width. This form of spacer is alternative to the use of a staple, as shown in Fig. 3, or the spacer head 9, shown in Fig. 6.

As a further modification of the spacer and attachment means, there is shown in Fig. 8 a staple W of greater width than the staple l4 projected through aligned holes in the'side'walls 5,

and flanges 8 of the channel and engageable with. the form board. .The legs of the staple i4 ex tend exteriorly of the portions 6 of the side walls and not only reinforce the channel against col-- lapse, but also hold it against spreading. The

staple 14 like the staple l4 not only serves as anattachment means but also reinforces the channel to enable it to resist the pressure of the concrete.

From the thatthere isthus provideda device of thecharacter described possessing the particular featuresof advantage beforeenumerated as desir-: able, but which obviously is susceptible of modifl-' cation in its form, proportions, detail construction and arrangement of parts withoutdeparting from theprinciple involved or sacrificing any of its advantages.
